• Functional biopolymers were developed via laccase biografting of natural compound.
• Biografting incorporates hydrophobic and antibacterial properties in biofibers.
• Biocomposites reinforced with biografted fibers showed improved properties.
Green surface modification of coconut fibers was performed using laccase biografting of eugenol for the development of antibacterial functionalities and fiber-reinforced polymer composites. Fourier transform infrared analysis, X-ray diffraction and surface morphology of grafted fibers were utilized to confirm the biografting of eugenol. Antibacterial, hydrophobicity and thermal properties were evaluated by colony forming unit (CFU) method, moisture absorption and thermogravimetric analysis, respectively. The grafted surfaces were found to be antibacterial, hydrophobic and thermally more stable. Grafted fibers were reinforced in a poly(butylene succinate) matrix to improve the mechanical properties of the biocomposites. The mechanical properties were improved even with a low content of biografted coconut fibers.
